A name for the fibrous form of sillimanite. Fibrolite is generally white to pale yellow and may occur in parallel bundles of fibers that seem to conform to the geometry of adjacent minerals, often in a gentle sweep of bent crystals. R.G. () Summary descriptions of mineral deposits by commodities in the Alice Springs Sheet Area. The Broken Hill and Deeps mines at Aggeneys have exploited one of a cluster of three main ore deposits, the other two being Swartberg/Black Mountain and lies some 16 km to the west of Gamsberg and 6 km east of Black Mountain. Aggeneys is located 60 km East of Pofadder and km West of Springbok within the Northern Cape Province of the Republic of South . Distinguished and successful diamond consultant in Namibia Born the eldest son of George and Vera Jenner-Clarke of Sutton, Surrey, Hugh and his younger brother (also named David) grew up in “Roselea”. George was a general dealer in groceries and fresh produce from a typical corner shop in the High Street, Sutton. Hugh attended a local Grammar School where he obtained his .

Geochemistry of bedded barite of the Mesoproterozoic Aggeneys-Gamsberg Broken Hill-type district, South Africa Article in Mineralium Deposita 42(5) May with 70 Reads. The purpose of the paper is to illustrate the geometrical distribution of the entire Namaqua-Natal Metamorphic Complex (NNMC). This is achieved by integrating information obtained by geological and geophysical mapping of Namaqua mobile belt outcrops, with data obtained by geophysical surveying of the region covered by Phanerozoic rocks to the south, east and offshore ().Cited by: 9. This chapter focuses on the various mobile belts of Southern Hemisphere. The Limpopo Belt is a strip of high-grade polymetamorphic and polytectonic terrane which strikes east-northeast for some km and separates the Rhodesian and Kaapvaal cratons by over by: 5. In , South Africa produced , barrels per day (bbl/d) of oil, of wh bbl/d was crude oil, and , bbl/d consisted of mostly synthetic liquids from coal and natural gas. Over 50 percent of South Africa’s oil consumption is imported. In , South Africa consumed , bbl/d of oil, and imported , bbl/d of oil.

Vertical, near surface increases in REE concentrations correlate with replacement of REE(±Sr,Ca,Na,Ba) carbonate minerals by Ca-REE fluorocarbonate minerals, dissolution of matrix calcite, development of Fe- and Mn-rich gossan, crystallization of cerianite and accompanying negative Ce anomalies in secondary fluorocarbonates and phosphates, and.
